Walkthrough

BitMediaQuery now supports direct content rendering, default match state, match-state access, expanded screen-query ranges, improved JavaScript listener lifecycle handling, and broader media-query examples and tests.

Changes

MediaQuery improvements

Layer / File(s) Summary
Query contracts and breakpoint generation
src/BlazorUI/Bit.BlazorUI/Components/Utilities/MediaQuery/BitScreenQuery.cs, src/BlazorUI/Bit.BlazorUI/Components/Utilities/MediaQuery/BitMediaQuery.ts
Six inclusive range queries were added. Screen queries now use screen and and runtime breakpoint values. Invalid queries and callback failures are handled.
Component rendering and lifecycle
src/BlazorUI/Bit.BlazorUI/Components/Utilities/MediaQuery/BitMediaQuery.razor, src/BlazorUI/Bit.BlazorUI/Components/Utilities/MediaQuery/BitMediaQuery.razor.cs
DefaultMatched, NoWrapper, and IsMatched were added. Rendering, query changes, element-id changes, callback handling, and disposal were updated.
Runtime behavior validation
src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Utilities/MediaQuery/BitMediaQueryTests.cs
Tests cover rendering states, callbacks, match state, query precedence, setup and disposal, identifier changes, visibility, and direct rendering.
Feature demonstrations
src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Utilities/MediaQuery/BitMediaQueryDemo.razor, src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Utilities/MediaQuery/BitMediaQueryDemo.razor.cs
The demo documents and shows range queries, theme breakpoints, custom media features, NoWrapper, DefaultMatched, OnChange, and IsMatched.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 2c551

The updated BitMediaQuery behavior can select the wrong themed breakpoint when NoWrapper content has a matching id, and a delayed media-query notification may update state or call OnChange after the listener is replaced or disposed. The PR is mergeable with explicit owner awareness and follow-up for these bounded lifecycle and breakpoint-resolution risks.

Poem

A rabbit checks the screen with care
New breakpoints hop through the air
No wrapper holds the view
Match states tell what’s true
Tests guard every query there

- Line 6: Update the BitMediaQuery NoWrapper path to pass an explicit no-wrapper
scope flag into JavaScript, and make resolveBreakpoints select
document.documentElement when that flag is set instead of resolving from the
matching component Id element. Add coverage using NoWrapper, direct child
content with the same Id, and themed breakpoints to verify document-root
resolution.
